JTD (uniJet Turbo Diesel) is Fiat Group's term for its current common rail turbodiesel engine range. The MultiJet name is used in the second generation JTD common rail units. Most of the Fiat, Alfa Romeo and Lancia range has JTD engines. Ownership of some Fiat JTD designs is shared with General Motors as part of a settlement of the failed merger between the two auto conglomerates. GM Powertrain Europe group in Turin, Italy manages their interest in these engines. Some PSA Peugeot Citroën diesel engines are also rebadged as JTD. A new generation JTD engine, Multijet II is under development and will be available in 2009, the Fiat Powertrain Technologies sees its very important step in diesel technology. This new technology will be first available for the 1.3 litre JTD engine.[1]


A small 1.3 L (1248 cc) version (called the SDE, Small Diesel Engine) is produced in Bielsko-Biała, Poland. The Multijet 75 PS version was chosen in 2005 as the International Engine of the Year in the 1-litre to 1.4-litre category.

There are four versions of this engine: a 70 PS (69 hp/51 kW), a 75 PS (74 hp/55 kW) (used in the Fiat Punto, Panda, Palio / Albea, Fiat Idea, Opel Corsa / Combo, Opel Meriva and Suzuki Swift), a variable inlet geometry 90 PS (89 hp/66 kW) (used in the new Fiat Grande Punto, Fiat Linea, Opel Corsa and Opel Astra), and a 105 PS (104 hp/77 kW) is available to Lancia Ypsilon. At the time of the launch this was the smallest four-cylinder diesel engine available and has a fuel consumption of 3.3 L/100 km (86 mpg-imp; 71 Template:Convert/fourmregb) in some applications. The engine is able to meet Euro IV pollution standards without the use of a diesel particulate filter.

In January 2008 Tata Motors introduced new Indica V3 model, which features new Quadra-Jet branded version of this engine.[2]



A 1.6 L (1598 cc) version of the engine, with a maximum power output of 120 PS (118 hp/88 kW) was announced for 2006.[3] The new 1.6 JTD diesel (105 PS) was released December 2007, it came in spring 2008 as 120 PS version.[4]



The most common JTD engine is the 1.9 L (1910 cc) straight-4 found in the Fiat Punto, Doblò, Stilo and Croma.

The first car that used this engine was Alfa Romeo 156 in 1997 (105 PS (104 hp/77 kW)), making it the world's first common-rail Diesel passenger car. In 1999 it was introduced with the Fiat Punto and Fiat Brava/Fiat Bravo/Fiat Marea. The engine block weighs approximately 125 kg (276 lb).

The Multijet second generation features a common-rail design and is available with four different power outputs. The 8-valve version has 100 PS (99 hp/74 kW), 120 PS (118 hp/88 kW) or 130 PS (128 hp/96 kW), the last two with variable inlet geometry; and the 16-valve version has 150 PS (148 hp/110 kW).

Opel also uses a version of this engine. Their CDTI engine, manufactured in Pratola Serra, Italy and Kaiserslautern, Germany, is the product of the half-decade joint venture between GM and Fiat. It is used in the Vectra, Signum, Astra, Zafira, Cadillac BLS and Suzuki SX4 as well as some Saabs marked as TiD and TTiD (twinturbo version).


1.9 Twin Turbo

Fiat Powertrain Technologies released information about new twin stage turbo (twin turbo) version of this engine in summer 2007, engine is available with two power levels, first one is producing 180 PS (178 hp/132 kW) and second one 190 PS (187 hp/140 kW), both have a maximum torque output of 400 N·m (295 lb·ft) at 2000 rpm. 180 PS version production started summer 2007. The engine weights approximately 185 kilograms (410 lb). This engine will be sold both to Fiat Group Automobiles and other brands, but the 190 PS (140 kW; 187 hp) version is reserved only to Fiat Group Automobiles.[5]



A new 2 litre (1956 cc) Multijet diesel was introduced in third generation Lancia Delta in summer 2008. At its first version this engine produces 165 PS (121 kW; 163 bhp).


2.0/2.2 (PSA)

The 2.0 JTD (1997 cc), used on Fiat Scudo, is not actually a Fiat engine, but rather a rebadged PSA DW10 engine.

The related 2.2 M-JET (2179 cc) used on Lancia Phedra and Fiat Ulysse is rebadged version of PSA DW12 engine, it produces 130 PS (96 kW). In January 2008 was introduced a new version with 170 PS (125 kW).



The 2.3 Multijet (2287 cc) was developed by Iveco and is available in two versions 120 MultiJet (Sofim FI AE048ID) and 130 MultiJet (Sofim FI AE048IN 2287), these engines produces 120 PS (88 kW) and 130 PS (96 kW).

The 2.4 L (2387 cc) straight-5 version is based on the 2.4 124 PS (122 hp/91 kW) 5 cylinder TD engine as used in the Mk1 Fiat Marea. The JTD version benefits from the solid build of the TD block, and an improved head/injection system. There are 2 versions of the 2.4JTD, the 10-valve as used in the Fiat Marea 130 JTD and the earlier Alfa Romeo 156 diesels where it was available as 136 PS (134 hp/100 kW),140 PS (138 hp/103 kW), 150 PS (148 hp/110 kW) and later a 20-valve version 175 PS (173 hp/129 kW) as used in the later (2003>) Alfa Romeo 156 as well as some Lancia vehicles.

It was designed for transverse front-wheel drive use and was deemed too long and tall for widespread use in other GM or Fiat products. The multijet variant of this engine, capable for 200 PS (197 hp/147 kW), is currently used in the Alfa Romeo 159, Alfa Romeo Brera and Fiat Croma. The latest version of this engine produces 210 PS (207 hp/154 kW) and 400 N·m (295 lb·ft) at 1500 rpm, and is used in Alfa Romeo vehicles.[6]



The 2.8 JTD (2798 cc) made by Iveco (Sofim) was used in second generation Fiat Ducato, it produces 127 PS (93 kW) or 146 PS (144 hp/107 kW). The 160 MultiJet Power, introduced in 2007, saw displacement increased to 3.0 L (2999 cc). This engine produces 157 PS (115 kW) in Fiat-badged models.
